Fishing Isojärvi
perch, pike and burbot sit at the top of the food chain in Isojärvi, carried by whitefish. The clearer water makes the fish wary — and rewards a careful presentation.
Every session at Isojärvi is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.
